Description
t ~613 SELF-ALIGNING VEHICLE DOO~ EJIN~
This invention relates to hinges and more particularly to a self-aligning pin and bushing hinge with - a spherical bushing and socket hinge to compensate for any misalignment of the door hinges.
Door hinges normally are mounted on the door frame and support the door in at least two place. Hinges normally lie essentially on a common axis to allow the door to swing freely. The doors on a vehicle cab are designed for reasonably close tolerances, b~t due to the use of sheet metal and during the process of fabrication variations affecting the alignment of the hinges occur.
Since it is difficult to always have perfect alignment and economically not feasible to maintain close tolerances, applicant's invention provides for an alternative. One hinge utilizes a spherical bushing seated in a socket to allow universal movement of the bushing within the socket.
The spherical bushing may be on the upper or lower hinge.
The bushing embraces a shaft on one-end of the door, while the other end of the door is supported by a pivotal pin and bushing hinge. Any misalignment is compensated for through the spherical bushing.
U.SO patent 3,874,027 and U.S. patent 4,16~,097 illustrate hinges used on doors and a vehicle cab similar to that used on the conventional tractor. The devices in these patents, however, do not use the spherical bushing and socket to accomodate minor misalignment of the hinges on the cab door as set forth in the applicant's invention.
It is an object of this invention to provide door hinges in which one of the hinges pivots abou~ a pin while the second hinge includes a spherical bushing mounted in a socket to accommodate any misalignment between the two hinges.
It is another object of this invention in which one hinge pivots on a pin while the second hinge pivots through a spherical bushing to accommodate for any misalignment of the hinges and also to facilitate assembly.
.
The objects of this invention are accomplished by providing a door ~ith a shaft extending above the door panel to be received within a cylindrical opening in the center of a spherical bushing. The spherical bushing is mounted in a socket to provide universal movement of the upper door hinge. The lower door hinge is connected by inserting a pin in a bushing permitting a pivotal movement of the door relative to the door frame.
The hinges permit ease in assembling ana mounting of the door by intially inserting the shaft into the spherical bushing and pressing it upwardly until the upper door is aligned and swinging the lower door to align the lower hinge and position the pin in the lower hinge assembly.
In one aspect of the present invention, there is provided self-aligning door hinges for a vehicle com-prising, a door pillar, a spherical bushing defining a central opening, a socket mounted on said pillar receiving said spherical bushing for universal movement of said spherical bushing, a door, a shaft connected to said door and extending from said door for reception in said spherical bushing forming a hinge of universal movement between said door and said pillar, first sleeve means mounted on said door pillar, means defining a door supporting surface on said first sleeve means, second sleeve means including a mating door carrying surface mounted on said door, a pin positioned in said first and second sleeve means when aligned therehy providing a hinge between said pillar and door and defining with the spherical bushing hinge the hinge axis on said door.
In a further aspect of the present invention, there is provided a method of hanging a door on a vehicle having a spherical bushing hinge and a sleeve bushing hinge having door supporting surfaces thereon 35 - comprising the steps of: aligning a shaft on said door for reception in the spherical bushing of the spherical bushing hinge, inserting the shaft into said spherical bushing for assembling the spherical bushing hinge of ~,, i l 3
